Abstract
CD8+ exhausted T cells (CD8+ Tex) played a vital role in the progression and therapeutic response of cancer. However, few studies have fully clarified the characters of CD8+ Tex related genes in ovarian cancer (OC). The CD8+ Tex related prognostic signature (TRPS) was constructed with integrative machine learning procedure including 10 methods using TCGA, GSE14764, GSE26193, GSE26712, GSE63885 and GSE140082 dataset. Several immunotherapy benefits indicators, including Tumor Immune Dysfunction and Exclusion (TIDE) score, immunophenoscore (IPS), TMB score and tumor escape score, were used to explore performance of TRPS in predicting immunotherapy benefits of OC. The TRPS constructed by Enet (alpha = 0.3) method acted as an independent risk factor for OC and showed stable and powerful performance in predicting clinical outcome of patients. The C-index of the TRPS was higher than that of tumor grade, clinical stage, and many developed signatures. Low TRPS score indicated a higher level of CD8+ T cell, B cell, macrophage M1, and NK cells, representing a relative immunoactivated ecosystem in OC. OC patients with low risk score had a higher PD1&CTLA4 immunophenoscore, higher TMB score, lower TIDE score and lower tumor escape score, suggesting a better immunotherapy response. Moreover, higher TRPS score indicated a higher score of cancer-related hallmarks, including angiogenesis, EMT, hypoxia, glycolysis, and notch signaling. Vitro experiment showed that ARL6IP5 was downregulated in OC tissues and inhibited tumor cell proliferation. The current study constructed a novel TRPS for OC, which could serve as an indicator for predicting the prognosis, immune infiltration and immunotherapy benefits for OC patients.

Abstract
OBJECTIVE To develop a method for accurate identification of multiscale carotid plaques in ultrasound images. METHODS We proposed a two-stage carotid plaque detection method based on deep convolutional neural network (SM-YOLO).A series of algorithms such as median filtering, histogram equalization, and Gamma transformation were used to preprocess the dataset to improve image quality. In the first stage of the model construction, a candidate plaque set was built based on the YOLOX_l target detection network, using multiscale image training and multiscale image prediction strategies to accommodate carotid artery plaques of different shapes and sizes. In the second stage, the Histogram of Oriented Gradient (HOG) features and Local Binary Pattern (LBP) features were extracted and fused, and a Support Vector Machine (SVM) classifier was used to screen the candidate plaque set to obtain the final detection results. This model was compared quantitatively and visually with several target detection models (YOLOX_l, SSD, EfficientDet, YOLOV5_l, Faster R-CNN). RESULTS SM-YOLO achieved a recall of 89.44%, an accuracy of 90.96%, a F1-Score of 90.19%, and an AP of 92.70% on the test set, outperforming other models in all performance indicators and visual effects. The constructed model had a much shorter detection time than the Faster R-CNN model (only one third of that of the latter), thus meeting the requirements of real-time detection. CONCLUSION The proposed carotid artery plaque detection method has good performance for accurate identification of carotid plaques in ultrasound images.

Abstract
BACKGROUND Early-onset pancreatic cancer (EOPC) in younger populations (age≤50 y) is likely to be a more aggressive phenotype characterized by poor differentiation. The emerging analysis of the global burden of EOPC is limited and outdated. AIM To systematically investigate the burden and trend of EOPC based on global populations. METHODS In this systematic analysis based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we present the number of cases, age-standardized rates (ASRs) per 100,000 population, and risk factors for 204 countries and territories. The average annual percentage changes (AAPCs) for the incidence, mortality, and disability-adjusted life-years (DALYs) of EOPC were calculated using joinpoint regression analysis. RESULTS According to the GBD 2019 estimates, there were 36,852 new cases of EOPC and 32,004 related deaths. East Asia had the highest number of cases, with 11,401 incidences and 10,149 deaths. The ASRs were 0.94 per 100,000 individuals for incidence and 0.81 per 100,000 for mortality. From 1990 to 2019, the age-standardized incidence increased by 46.9%, mortality increased by 44.6%, and DALYs increased by 41.9% globally. In trend analysis, the global incidence (AAPC, 1.26), mortality (AAPC, 1.24), and DALYs (AAPC, 1.25) of EOPC showed an increasing pattern. The ASRs of incidence, mortality, and DALYs of EOPC in Africa, America, and Asia exhibited a continuous upward trend, while the trend in Europe was fluctuating. Asian males exhibited the fastest growth in incidence (AAPC, 2.15) and mortality (AAPC, 2.13), whereas males in the Americas experienced the slowest increase in new cases (AAPC, 0.72) and deaths (AAPC, 0.67). A certain proportion of EOPC DALYs were attributable to known risk factors: tobacco smoking (13.3%), high body-mass index (BMI, 5.6%), and high fasting plasma glucose (FPG, 3.2%). Integrating the socio-demographic index (SDI), ASRs of incidence and mortality initially increased with rising SDI, reaching a peak in central Europe (1.5 per 100,000 CONCLUSIONS The findings offer valuable insights into the global distribution and magnitude of the EOPC burden. The burden is increasing at a rapid pace worldwide, particularly in Asia, and is notably high in central and eastern Europe. This highlights the need for additional preventive control efforts targeting high-risk populations.

Abstract
BACKGROUND Textbook outcomes (TOs) have been used to assess the quality of surgical treatment for many digestive tumours but not ampullary carcinoma (AC). AIM To discuss the factors associated with achieving a TO and further explore the prognostic value of a TO for AC patients undergoing curative pancreaticoduodenectomy (PD). METHODS Patients who underwent PD at the China National Cancer Center between 1998 and 2020 were identified. A TO was defined by R0 resection, examination of ≥ 12 Lymph nodes, no prolonged hospitalization, no intensive care unit treatment, no postoperative complications, and no 30-day readmission or mortality. Cox regression analysis was used to identify the prognostic value of a TO for overall survival (OS) and recurrence-free survival (RFS). Logistic regression was used to identify predictors of a TO. The rate of a TO and of each indicator were compared in patients who underwent surgery before and after 2010. RESULTS Ultimately, only 24.3% of 272 AC patients achieved a TO. A TO was independently associated with improved OS [hazard ratio (HR): 0.443, 95% confidence interval (95%CI): 0.276-0.711, P = 0.001] and RFS (HR: 0.379, 95%CI: 0.228-0.629, P < 0.001) in the Cox regression analysis. Factors independently associated with a TO included a year of surgery between 2010 and 2020 (OR: 4.549, 95%CI: 2.064-10.028, P < 0.001) and N1 stage disease (OR: 2.251, 95%CI: 1.023-4.954, P = 0.044). In addition, the TO rate was significantly higher in patients who underwent surgery after 2010 (P < 0.001) than in those who underwent surgery before 2010. CONCLUSION Only approximately a quarter (24.3%) of AC patients achieved a TO following PD. A TO was independently related to favourable oncological outcomes in AC and should be considered as an outcome measure for the quality of surgery. Further multicentre research is warranted to better elucidate its impact.

Abstract
BACKGROUND The preoperative total bilirubin-albumin ratio (TBAR) and fibrinogen-albumin ratio (FAR) have been proven to be valuable prognostic factors in various cancers. AIM To detect the prognostic value of TBAR and FAR in ampullary adenocarcinoma (AC) patients who underwent curative pancreaticoduodenectomy. METHODS AC patients who underwent curative pancreaticoduodenectomy in the National Cancer Center of China between 1998 and 2020 were retrospectively reviewed. The prognostic cutoff values of TBAR and FAR were determined through the best survival separation model. Then, a novel prognostic score combining TBAR and FAR was calculated and validated through the logistic regression analysis and Cox regression analysis. RESULTS A total of 188 AC patients were enrolled in the current study. The best cutoff values of TBAR and FAR for predicting overall survival were 1.7943 and 0.1329, respectively. AC patients were divided into a TBAR-low group (score = 0) vs a TBAR-high group (score = 1) and a FAR-low group (score = 0) vs a FAR-high group (score = 1). The total score was calculated as a novel prognostic factor. Multivariable logistic regression analysis revealed that a high score was an independent protective factor for recurrence [score = 1 vs score = 0: Odds ratio (OR) = 0.517, P = 0.046; score = 2 vs score = 0 OR = 0.236, P = 0.038]. In addition, multivariable survival analysis also demonstrated that a high score was an independent protective factor in AC patients (score = 2 vs score = 0: Hazard ratio = 0.230, P = 0.046). CONCLUSION A novel prognostic score based on preoperative TBAR and FAR has been demonstrated to have good predictive power in AC patients who underwent curative pancreaticoduodenectomy. However, more studies with larger samples are needed to validate this conclusion.

Abstract
BACKGROUND According to the 2019 World Health Organization (WHO) classification of gastric neuroendocrine neoplasms, gastric neuroendocrine carcinoma (GNEC) can be further divided into gastric large-cell neuroendocrine carcinoma (GLNEC) and gastric small-cell neuroendocrine carcinoma (GSNEC). Whether the prognoses of the two types have a discrepancy has long been disputed. METHOD We collected patients diagnosed with GLNEC or GSNEC in the National Cancer Center of China between January 2000 and December 2020. The characteristics and survival outcomes were compared between the two groups. We further verified our conclusion using the SEER dataset. RESULTS A total of 114 GNEC patients, including 82 patients with GLNEC and 32 patients with GSNEC, have completed treatment in our hospital. Clinicopathologic differences were not observed between patients with GSNEC and GLNEC concerning the sex, age, body mass index, Charlson Comorbidity Index, tumor location, tumor size, stage, treatment received, the expression of neuroendocrine markers (CD56, Chromogranin A, synaptophysin), and score on the Ki-67 index. The 1-year, 3-year, and 5-year overall survival rates of GLNEC and GSNEC were 89.0%, 60.5%, and 52.4%, and 93.8%, 56.3%, and 52.7%, which showed no statistically significant differences. This result was confirmed further by using the SEER dataset after the inverse probability of treatment weighting. CONCLUSIONS Although with different cell morphology, the comparison of prognosis between the GLNEC and GSNEC has no significant statistical difference.

Abstract
BACKGROUND Both hepatoid adenocarcinoma of the stomach (HAS) and neuroendocrine differentiation (NED) are rare histological subtypes of gastric cancer with unique clinicopathological features and unfavorable outcomes. HAS with NED is even rarer.
CASE SUMMARY Here, we report a 61-year-old man with HAS with NED, as detected by gastric wall thickening by positron emission tomography/computed tomography for a pulmonary nodule. Distal gastrectomy was performed, and pathological examination led to the diagnosis of HAS with NED. However, liver metastases occurred 6 mo later despite adjuvant chemotherapy, and the patient died 27 mo postoperatively.
CONCLUSION We treated a patient with HAS with NED who underwent adjuvant chemotherapy after radical surgery and still developed liver metastases. We first report the detailed processes of the treatment and development of HAS with NED, providing an important reference for the clinical diagnosis and treatment of this condition.

BACKGROUND The effect of perioperative blood transfusion (PBT) on the prognosis of ampullary carcinoma (AC) is still debated. AIM To explore the impact of PBT on short-term safety and long-term survival in AC patients who underwent pancreaticoduodenectomy. METHODS A total of 257 patients with AC who underwent pancreaticoduodenectomy between 1998 and 2020 in the Cancer Hospital, Chinese Academy of Medical Sciences, were retrospectively analyzed. We used Cox proportional hazard regression to identify prognostic factors of overall survival (OS) and recurrence-free survival (RFS) and the Kaplan-Meier method to analyze survival information. RESULTS A total of 144 (56%) of 257 patients received PBT. The PBT group and nonperioperative blood transfusion group showed no significant differences in demographics. Patients who received transfusion had a comparable incidence of postoperative complications with patients who did not. Univariable and multivariable Cox proportional hazard regression analyses indicated that transfusion was not an independent predictor of OS or RFS. We performed Kaplan-Meier analysis according to subgroups of T stage, and subgroup analysis indicated that PBT might be associated with worse OS (P < 0.05) but not RFS in AC of stage T1. CONCLUSION We found that PBT might be associated with decreased OS in early AC, but more validation is needed. The reasonable use of transfusion might be helpful to improve OS.

Abstract
BACKGROUND Growing evidence shows that pancreatic tumors in different anatomical locations have different characteristics, which have a significant impact on prognosis. However, no study has reported the differences between pancreatic mucinous adenocarcinoma (PMAC) in the head vs the body/tail of the pancreas.
AIM To investigate the differences in survival and clinicopathological characteristics between PMAC in the head and body/tail of pancreas.
METHODS A total of 2058 PMAC patients from the Surveillance, Epidemiology, and End Results database diagnosed between 1992 and 2017 were retrospectively reviewed. We divided the patients who met the inclusion criteria into pancreatic head group (PHG) and pancreatic body/tail group (PBTG). The relationship between two groups and risk of invasive factors was identified using logistic regression analysis. Kaplan-Meier analysis and Cox regression analysis were conducted to compare the overall survival (OS) and cancer-specific survival (CSS) of two patient groups.
RESULTS In total, 271 PMAC patients were included in the study. The 1-year, 3-year, and 5-year OS rates of these patients were 51.6%, 23.5%, and 13.6%, respectively. The 1-year, 3-year, and 5-year CSS rates were 53.2%, 26.2%, and 17.4%, respectively. The median OS of PHG patients was longer than that of PBTG patients (18 vs 7.5 mo, P < 0.001). Compared to PHG patients, PBTG patients had a greater risk of metastases [odds ratio (OR) = 2.747, 95% confidence interval (CI): 1.628-4.636, P < 0.001] and higher staging (OR = 3.204, 95% CI: 1.895-5.415, P < 0.001). Survival analysis revealed that age < 65 years, male sex, low grade (G1-G2), low stage, systemic therapy, and PMAC located at the pancreatic head led to longer OS and CSS (all P < 0.05). The location of PMAC was an independent prognostic factor for CSS [hazard ratio (HR) = 0.7, 95%CI: 0.52-0.94, P = 0.017]. Further analysis demonstrated that OS and CSS of PHG were significantly better than PBTG in advanced stage (stage III-IV).
CONCLUSION Compared to the pancreatic body/tail, PMAC located in the pancreatic head has better survival and favorable clinicopathological characteristics.

Abstract
There has been a long-standing controversy regarding the number of lymph nodes (LNs) examined intraoperatively for accurate lymphatic staging and significantly better survival of patients with pancreatic ductal adenocarcinoma (PDAC), and no consensus has been reached for the elderly with the age of over 75 years. Given these, the present study aims to investigate the appropriate number of examined lymph nodes (ELNs) for elderly patients mentioned above. In this study, population-based data on 20,125 patients in 2000 to 2019 from the Surveillance, Epidemiology, and End Results database were reviewed retrospectively. The eighth edition staging system of the American Joint Committee on Cancer (AJCC) was applied. Propensity score matching (PSM) was performed to reduce the effects of multiple biases. By using binomial probability law and maximally selected rank statistics, the minimum number of ELN (MNELN) for accurate nodal involvement assessment and optimal ELN number for significantly better survival were calculated, respectively. In addition, Kaplan-Meier curves and Cox proportional hazard regression models were constructed for further survival analysis. As a result, 6623 patients were enrolled in total in the study. Elderly patients had fewer lymph node metastases and a smaller lymph node ratio (LNR) (all P<0.05). However, poorer overall survival (OS) and cancer-specific survival (CSS) of elderly patients were observed in each pN stage (all P<0.05), except for CSS in N2. The proportions of N2 and N0 stages increased and decreased respectively with increasing number of ELN significantly. MNELN for accurate nodal assessment was 19 according to binomial probability law, and the optimal ELN number for significantly better survival was 17. Additionally, the number of ELN (<17 or ≥17) was also considered a strong prognostic predictor for elderly PDAC patients (≥75 years) in the Cox proportional hazard regression model (Overall survival: hazard ratio [HR]=0.74, 95% confidence interval [CI]: 0.65-0.83, P<0.001; Cancer-specific survival: HR=0.75, 95% CI: 0.66-0.85, P<0.001). In conclusion, extended lymphadenectomy is suitable for elderly PDAC patients undergoing curative-intent surgery owing to an accurate assessment of nodal status and improved long-term prognosis. However, a random, prospective clinical trial is warranted before the recommendation of extended lymphadenectomy for the elderly.

Abstract
BACKGROUND The tumor microenvironment (TME) plays an important role in the growth and expansion of gastric cancer (GC). Studies have identified that CD93 is involved in abnormal tumor angiogenesis, which may be related to the regulation of the TME.
AIM To determine the role of CD93 in GC.
METHODS Transcriptomic data of GC was investigated in a cohort from The Cancer Genome Atlas. Additionally, RNA-seq data sets from Gene Expression Omnibus (GSE118916, GSE52138, GSE79973, GSE19826, and GSE84433) were applied to validate the results. We performed the immune infiltration analyses using ESTIMATE, CIBERSORT, and ssGSEA. Furthermore, weighted gene co-expression network analysis (WGCNA) was conducted to identify the immune-related genes.
RESULTS Compared to normal tissues, CD93 significantly enriched in tumor tissues (t = 4.669, 95%CI: 0.342-0.863, P < 0.001). Higher expression of CD93 was significantly associated with shorter overall survival (hazard ratio = 1.62, 95%CI: 1.09-2.4, P = 0.017), less proportion of CD8 T and activated natural killer cells in the TME (P < 0.05), and lower tumor mutation burden (t = 4.131, 95%CI: 0.721-0.256, P < 0.001). Genes co-expressed with CD93 were mainly enriched in angiogenesis. Moreover, 11 genes were identified with a strong relationship between CD93 and the immune microenvironment using WGCNA.
CONCLUSION CD93 is a novel prognostic and diagnostic biomarker for GC, that is closely related to the immune infiltration in the TME. Although this retrospective study was a comprehensive analysis, the prospective cohort studies are preferred to further confirm these conclusions.

Abstract
The minimum number of lymph nodes to be examined during pancreaticoduodenectomy (PD) for patients with ampullary adenocarcinoma (AC) is still debatable due to limited clinical data. Therefore, here we explored the relationship between the number of examined lymph node (ELN) and the current N staging (American Joint Committee on Cancer staging system, AJCC, 8 edition) after PD for AC as well as determined the minimum number of examined lymph nodes (MNELN) to ensure the accurate detection of nodal involvement. Patients underwent PD for AC in the National Cancer Center cohort of China (NCC cohort of China) from 1998 to 2020 and in the Surveillance, Epidemiology, and End Results database (SEER database) from 2010 to 2018 were retrospectively reviewed, and a total of 452 eligible patients were included in this study. The MNELN was evaluated by binomial probability law and best survival separation methods. Furthermore, the cut-off value of MNELN was validated in the NCC cohort of China using Least Absolute Shrinkage and Selection Operator (LASSO) regression. Our analysis indicated that the median number of ELN was 14, and the number of ELN was positively correlated with N stage. The MNELN was 16, whereas the best survival separation of ELN was 38 in node-positive patients and 3 in node-negative patients. In the validation cohort, the number of 16 ELNs was identified as a predictive variable for lymph node metastasis with nonzero coefficients in the LASSO-logistic regression model. Together, we concluded that a greater number of ELN was associated with more accurate nodal status assessment in PD for AC patients. A minimum of 16 lymph nodes were required to during PD in AC patients.

Abstract
BACKGROUND Serum lipids (SLs), the prominent indicators of lipid metabolism, produce an intricate impact on proliferation, invasion, and metastasis of cancer cells. However, the effects of serum lipids on the prognosis of ampullary adenocarcinoma (AC) have not been investigated. METHODS Patients with AC in the National Cancer Center of China between January 1998 and December 2020 were retrospectively reviewed. Survival analysis for overall survival (OS, Time from operation to death) and recurrence-free survival (RFS, Time from operation to first-time recurrence) was performed using Kaplan-Meier analysis and Cox proportional hazards models. RESULTS A total of 232 AC patients were enrolled into the study. SLs levels were significantly lower in patients with vascular invasion compared to those without (all p < 0.05). The 1-year, 3-year, and 5-year OS rates for AC patients were 86.1%, 64.1%, and 47.6% and 75.8%, 54.8%, and 46.5% for RFS. Biliary/pancreatic fistula (31.9%) and chemotherapy (81.4%) were the majority of postoperative complications and adjuvant therapy, respectively. According to Cox analysis, preoperative LDL-C was an independent prognostic factor for RFS (HR = 0.43, 95% CI: 0.21-0.85, p = 0.015), whereas no statistical significance existed in the analysis of HDL-C, TC, and TG. CONCLUSIONS High levels of preoperative LDL-C is a significant predictor of prolonged prognosis in AC patients, which was also observed to be a protective factor to reduce vascular invasion.

Abstract
As the predominant stroma cells of tumor microenvironment (TME), cancer associated fibroblasts (CAFs) are robust tumor player of different malignancies. However, less is known about the regulatory mechanism of CAFs on promoting progression of ovarian cancer (OvCA). In the present study, the conditioned medium of primary CAFs (CAF-CM) from OvCA was used to culture cell lines of epithelial ovarian cancer (EOC), and showed a potent role in promoting proliferation, migration and invasion of cancer cells. Mass spectrum (MS) analysis identified that Collapsin response mediator protein-2 (CRMP2), a microtubule-associated protein involved in diverse malignancies, derived from CAFs was a key regulator responsible for mediating these cell events of OvCA. In vitro study using recombinant CRMP2 (r-CRMP2) revealed that the protein promoted proliferation, invasion, and migration of OvCA cells through activation of hypoxia-inducible factor (HIF)-1α-glycolysis signaling pathway. The CRMP2 was abundantly expressed in OvCA, with a well correlation with metastasis and poor prognosis, as analyzed from 118 patients' samples. Inhibition of the CRMP2 derived from CAFs by neutralizing antibodies significantly attenuated the tumor size, weights, and metastatic foci numbers of mice in vivo. Our finding has provided a novel therapeutic clue for OvCA based on TME.

Abstract
BACKGROUND Gastric neuroendocrine carcinoma (GNEC) is a rare histological subtype of gastric cancer, which is categorized into small cell and large cell neuroendocrine carcinomas. It is characterized by strong invasiveness and poor prognosis. Mixed large and small cell neuroendocrine carcinoma (L/SCNEC) is an extremely rare pathological type of gastric cancer, and there have been no reports on this situation until now.
CASE SUMMARY Herein, we first present a 57-year-old patient diagnosed with L/SCNEC of the stomach. A 57-year-old Chinese male presented with epigastric discomfort. Outpatient gastroscopic biopsy was performed, and pathological examination revealed that the cardia was invaded by adenocarcinoma. The patient underwent laparoscopic-assisted radical proximal subtotal gastrectomy and was diagnosed with L/SCNEC. He refused adjuvant treatment and was followed up every 3 mo. Eight months after the operation, the patient showed no evidence of local recurrence or distant metastasis.
CONCLUSION We advocate conducting further genomic studies to explore the origin of gastric large cell and small cell neuroendocrine carcinoma and using different chemotherapy schemes according to large or small cell neuroendocrine carcinoma of the stomach for clinical research to clarify the heterogeneity of GNEC and improve the prognosis of patients with GNEC.

Abstract
Argonaute proteins (Agos) from thermophiles function as endonucleases via guide-target base-pairing cleavage for host defense. Since guides play a key role in regulating the catalytic specificity of Agos, elucidating its underlying molecular mechanisms would promote the application of Agos in the medical sciences. Here, we reveal that an Ago from Pyrococcus furiosus (PfAgo) showed a stepwise endonuclease activity, which was demonstrated through a double-stranded DNA cleavage directed by a single guide DNA (gDNA) rather than a canonical pair of gDNAs. We validated that the cleavage products with 5'-phosphorylated ends can be used as a new guide to induce a new round of cleavage. Based on the reprogrammable capacity of Ago's stepwise activity, we established a rapid and specific platform for unambiguous multiplex gene detection, termed Renewed-gDNA Assisted DNA cleavage by Argonaute (RADAR). Combined with a pre-amplification step, RADAR achieved sensitivity at the femtomolar level and specificity with at least a di-nucleotide resolution. Furthermore, RADAR simultaneously discriminated among multiple target sequences simply by corresponding multiple guides. We successfully distinguished four human papillomavirus serotypes from patient samples in a single reaction. Our technique, based on the unique properties of Ago, provides a versatile and sensitive method for molecular diagnosis.

Abstract
CREBBP, in short CBP, has been reported to be involved in tumorigenesis in various cancers, but its role in ovarian cancer remains largely unexplored. In our study, survival analysis of CBP in patients with ovarian cancer was conducted using the Kaplan-Meier Plotter database, then we utilized specific shRNA targeting CREBBP to block the expression of CBP, and detected its effect on cell proliferation and chemo-sensitivity in ovarian cancer cells. The results showed that high expression of CBP was correlated with poor prognosis in ovarian cancer patients. CREBBP knockdown in ovarian cancer cells significantly inhibited tumor proliferation both in vitro and in vivo. Moreover, CREBBP knockdown promoted chemo-sensitivity in ovarian cancer cells. Mechanism research further demonstrated that CREBBP knockdown attenuated unfolded protein response (UPR), which was mediated by PERK/ATF4/STC2 signaling pathway. Our research linked CBP and UPR in ovarian cancer and may provide new strategies for the clinical treatment of ovarian cancer.

Abstract
AIM Ghrelin, an endogenous ligand for the growth hormone secretagogue receptor (GHSR), has been found to be involved in the regulation of blood pressure; however, its effects in preeclampsia (PE) and the potential underlying mechanism remain poorly understood. In this study, we aimed to investigate the correlation between ghrelin and PE and reveal the possible mechanism underlying any relationship. METHODS The levels of ghrelin and VEGF in the plasma of 6 early-onset PE (EOPE), 6 late-onset PE (LOPE) and 12 healthy pregnant (HP) women were detected using enzyme-linked immunosorbent assay (ELISA). The recombinant plasmid, pCDH-ghrelin, was designed to overexpress ghrelin in human umbilical vein endothelial cells (HUVECs). We analyzed angiogenesis in vitro and investigated the mechanism using MTT assay, colony formation assay, transwell migration assay, Matrigel-induced tube formation assay and western blotting. RESULTS Ghrelin was significantly decreased in EOPE patients (P < 0.05) but elevated in LOPE patients compared to HP groups (P > 0.05). There was a significant decrease in plasma level of VEGF in EOPE and LOPE patients compared to the controls (P < 0.05). The proliferation, migration and tube formation ability of HUVECs were enhanced after transfection with pCDH-ghrelin. Ghrelin increased VEGF by activating the Jagged1/Notch2 pathway. CONCLUSION Our study uncovered that ghrelin has the potential to improve endothelial function by promoting angiogenesis through Jagged1/Notch2/VEGF pathway.

Abstract
Intrauterine adhesion is a severe complication after intrauterine operation, Various adjuvant therapies failed to improve clinical symptoms and pregnancy rates among patients with moderate-to-severe intrauterine adhesion. At present, hyaluronic acid gel is widely used in the primary prevention of adhesion after hysteroscopic adhesiolysis. However, its efficacy is still under debate. Therefore, the aim of this study was to systematically evaluate the efficacy of hyaluronic acid gel in preventing the recurrence of intrauterine adhesion after hysteroscopic adhesiolysis. The Cochrane Library, Embase, and PubMed databases were used to search for articles published before July 31, 2018, using the following terms: hyaluronic acid, intrauterine adhesions, Asherman's syndrome, IUA, hysteroscopy, and hysteroscopic adhesiolysis. Studies on therapies after hysteroscopic adhesiolysis were collected. The recurrence rate of and pregnancy rate in the presence of intrauterine adhesion after hysteroscopic adhesiolysis were analyzed by RevMan 5.3 software. A total of 6 articles were selected, which included 394 patients who were subjected to hysteroscopic adhesiolysis. The meta-analysis results showed that (1) no statistically significant difference was found between hyaluronic acid gel use and without its use on the score of intrauterine adhesion after hysteroscopic adhesiolysis [the mean difference (MD) = -0.89, 95% confidence interval (CI) (-2.53-0.76), P = 0.29], neither a statistically significant difference was observed between the same groups on the recurrence rate of intrauterine adhesion [odds ratio (OR) = 0.75, 95% CI (0.31-1.81), P = 0.53]; (2) subgroup analysis showed that hyaluronic acid gel could reduce the rate of intrauterine adhesion recurrence in randomized controlled trials [OR = -0.28, 95% CI (0.14-0.56), P = 0.0006]. However, the recurrence rate of intrauterine adhesion after the use of hyaluronic acid gel was not statistically significant in non-randomized controlled experiments [OR = 1.53, 95% CI (0.79-2.95), P = 0.21]; (3) hyaluronic acid gel did not result in a significant effect on pregnancy rate after intrauterine adhesion separation [OR = 2.02, 95% CI (0.53-7.66), P = 0.3]. In conclusion, hyaluronic acid gel could reduce the recurrence rate of intrauterine adhesion, but had no significant effect on the postoperative pregnancy rate.

Abstract
Irradiation induces severe damage in the hematopoietic system, which leads to bone marrow hyperplasia, pancytopenia, and aggravated tissue formation in bone marrow. Studies have shown that Toll-like receptor 4 (TLR4) has a protective effect against irradiation, but the underlying mechanism remains unclear. In this study, we used a TLR4 knockout (TLR4-/-) mouse irradiation model and found that the white blood cell and platelet counts in the peripheral blood of TLR4-/- mice recovered slowly after irradiation, with bone marrow hyperplasia and increased mortality. Additionally, we found that the proportion of CD11b+Gr1+ granulocytes in the peripheral blood and bone marrow of TLR4-/- mice was lower than that of wild-type mice after irradiation. Further, we found that the expression of NADPH Oxidases (NOXs) in the bone marrow was down-regulated after irradiation of TLR4-/- mice, and administration of the NOXs inhibitor VAS2870 reduced the proportion of CD11b+Gr1+ cells in the bone marrow and peripheral blood of wild-type mice after irradiation. Irradiation induced severe marrow adipocytes accumulation in TLR4-/- mice, TLR4 ligand lipopolysaccharide promoted proliferation and inhibited adipogenic differentiation of mesenchymal stromal cells. In summary, our data suggest that TLR4 promotes myeloid hyperplasia by up-regulating the expression of NOXs after irradiation, prohibits marrow adipogensis and increases the tolerance of mice to irradiation.

Abstract
BACKGROUND Intrauterine adhesions are a severe complication after miscarriage. Hyaluronic acid gel has been used to prevent intrauterine adhesions after miscarriage. OBJECTIVE To systematically evaluate the efficacy of adjuvant therapy with hyaluronic acid gel to prevent intrauterine adhesions after miscarriage. SEARCH STRATEGY The Cochrane Library, Embase and PubMed databases were searched for articles published before 31 July 2018 using the terms: ('hyaluronic acid gel' or 'gel') and ('dilatation and curettage' or 'D&C' or 'abortion' or 'miscarriage' or 'hysteroscopic') and ('intrauterine adhesions' or 'Asherman syndrome' or 'IUA' or 'endometrial injury' or 'intrauterine adhesion'). SELECTION CRITERIA Randomized controlled trials of hyaluronic acid gel therapy after miscarriage. DATA COLLECTION AND ANALYSIS Four studies were included in the meta-analysis (625 patients in total). Dichotomous outcomes were expressed as relative risk (RR) with 95 % confidence intervals (CI). Continuous variables were expressed as standardized mean differences (SMD). MAIN RESULTS Hyaluronic acid gel reduced the intrauterine adhesion scores after miscarriage (SMD -0.68, 95 % CI -1.08~-0.28; p = 0.0008) and the incidence of postoperative intrauterine adhesions after miscarriage (RR 0.44, 95 % CI 0.29~0.67; p = 0.0001). Subgroup analysis found that hyaluronic acid gel reduced the incidence of moderate and severe intrauterine adhesions after miscarriage (RR 0.18, 95 % CI: 0.07~0.47; p = 0.0004), but had no effect on the incidence of mild intrauterine adhesions (RR 0.77, 95 % CI 0.42~1.19; p = 0.19). Hyaluronic acid gel also improved the pregnancy rate after miscarriage (RR 1.94, 95 % CI 1.46~2.60; p < 0.00001). CONCLUSION Hyaluronic acid gel significantly reduced the incidence of moderate and severe intrauterine adhesions and significantly improved the pregnancy rate after miscarriage.

Abstract
Ovarian cancer is one of the three most deadly gynecological cancers, with the highest mortality rate. As the main cause of death, metastasis is considered to be a crucial factor that reduces the survival time of ovarian carcinoma patients. YWHAZ (also known as 14‑3‑3ζ) influences diverse vital cellular processes such as metabolism, signal transduction, apoptosis and cell cycle regulation. In the present study, we determined that YWHAZ is upregulated in ovarian cancers in contrast to normal tissues by immunohistochemical staining. High YWHAZ expression was found to be associated with TNM stage and metastasis‑free prognosis of ovarian cancer patients. Silencing of YWHAZ inhibited the proliferation and facilitated serum starvation‑induced apoptosis of ovarian cancer cells. Cell migration was also suppressed by YWHAZ silencing. Furthermore, using an in vivo metastatic model, we found that YWHAZ silence also inhibited ovarian cancer metastasis in vivo. Notably, glycolysis was clearly inhibited in YWHAZ‑silenced ovarian cancer cells as determined by lactate production assay and Seahorse XF analysis. YWHAZ also regulated the PI3K/Akt1/vimentin signaling pathway in ovarian cancer cells as detected by western blot analysis. Taken together, our results demonstrated that YWHAZ plays an important role in the progression of ovarian cancer and can be used as a potential target for the diagnosis and treatment of epithelial ovarian cancer.

Abstract
Epithelial ovarian cancer (EOC) is the major cause of deaths from gynecologic malignancies, and metastasis is the main cause of cancer related death. Collagen triple helix repeat containing-1 (CTHRC1) is a secreted protein that has the ability to inhibit collagen matrix synthesis. In this study, we found that high CTHRC1 expression was associated with poor prognosis of EOC. In vitro experiments showed that CTHRC1 promoted migration and invasion of ovarian cancer cells. CTHRC1 had no effect on ovarian cancer cells viability. Additionally, EGFR inhibitors reduced the promotion effects of CTHRC1 on EOC cell invasion. After silencing of CTHRC1, downregulated expression of phosphorylation of EGFR/ERK1/2/AKT was observed in ovarian cancer cells. Taken together, our results suggest a role for CTHRC1 in the progression of ovarian cancer and identified CTHRC1 as a potentially important predictor for human ovarian cancer prognosis.

Abstract
A missed abortion (MA) is an in utero death of the embryo or fetus before the 20th week of gestation with retained products of conception, and this condition is currently common in China. In order to discover novel biomarkers for MA, ultrahigh performance liquid chromatography was applied to study plasma metabolite profiles for 33 patients with MA and 29 control subjects. Thirty-seven differential plasma metabolites were found to discriminate between the two groups in the initial cohort (15 subjects with MA and 15 healthy controls). The feasibility of using these potential biomarkers to predict MA was further evaluated in the validation cohort (18 subjects with MA and 14 healthy controls) and 15 had an area under the receiver operating characteristic curve of >0.80, making them satisfactory. Tryptophan metabolism and sphingolipid metabolism were identified as important potential target pathways for MA using metabolic pathway impact analysis. Furthermore, three of the 15 satisfactory metabolites (glyceric acid, indole and sphingosine) were combined to establish a predictive model with 100% sensitivity and 100% specificity in the validation cohort. Taken together, these results suggest that MA results in significant disturbance of metabolism and those various novel biomarkers have satisfactory diagnostic and predictive power for MA.

Abstract
OBJECTIVE This study aims to explore the effect of Notch signaling depression on the receptor activator of nuclear factor kappa B ligand (RANKL)-induced osteoclastogenesis of RAW264.7 cells. METHODS Mice RAW264.7 cells were cultured and differentiated into osteoclasts with the induction of RANKL. The expressions of Notch1, Notch2, Deltal, Jagged1, Hes1, tartrate-resistant acid phosphatase (TRAP), and Cathepsin K genes during osteoclastogenesis were analyzed using real-time polymerase chain reaction. Osteoclast formation was analyzed using TRAP assay with suppression of Notch receptors by a selective γ-secretase inhibitor (GSI). RESULTS Notch1, Notch2, Delta1, Jagged1, and Hes1 expressions in RAW264.7 cells were upregulated following 50 ng · mL-RANKL stimulation for 3 d, concomitant with the expression of the osteoclast differentiation markers TRAP and Cathepsin K. Notch2 and Jagged1 had the most remarkable increase in the Notch family members. GSI inhibited RANKL-induced osteoclastogenesis of RAW264.7 cells and Hes1 expression dose-dependently. CONCLUSION Notch signaling activation may promote RANKL-induced osteoclastogenesis of RAW264.7 cells.

Abstract
Materials with core-shell structures have distinct properties that lend themselves to a variety of potential applications. Characterization of small particle core-shell materials presents a unique analytical challenge. Herein, single particles of solid-state materials with core-shell structures were measured using on-line aerosol time-of-flight mass spectrometry (ATOFMS). Laser 'depth profiling' experiments verified the core-shell nature of two known core-shell particle configurations (<2 μm diameter) that possessed inverted, complimentary core-shell compositions (ZrO2@SiO2 versus SiO2@ZrO2). The average peak area ratios of Si and Zr ions were calculated to definitively show their core-shell composition. These ratio curves acted as a calibrant for an uncharacterized sample – a metal-organic framework (MOF) material surround by silica (UiO-66(Zr)@SiO2; UiO = University of Oslo). ATOFMS depth profiling was used to show that these particles did indeed exhibit a core-shell architecture. The results presented here show that ATOFMS can provide unique insights into core-shell solid-state materials with particle diameters between 0.2-3 μm.

Abstract
PURPOSE OF INVESTIGATION To compare the therapeutic and side effects of using Californium252 (252Cf) neutron brachytherapy with neoadjuvant intra-arterial embolism chemotherapy in combination with surgery for treating Stage Ib2-IIb cervical cancers (CCs). MATERIALS AND METHODS Thirty-two Stage Ib2-IIb CC patients were enrolled and randomly divided into two groups from January 2007 to April 2010 in the present Hospital. Prior to surgery within four weeks, a total of 17 cases were treated with 252Cf neutron brachytherapy (700-800 cGy doses at point A) once a week (Group A), and 15 cases were treated by neoadjuvant intra-arterial embolism chemotherapy using a combination of bleomycin, carboplatin, and cyclophosphamide twice (Group B). The clinical symptoms and signs, side effects, and relapse condition follow up until July 2013 were compared between the two groups for the perioperation. RESULTS Reductions in tumor mass and CR+PR were not significantly different between the groups before the surgery (p > 0.05). Abdominal pain and pelvic adhesions were significantly more severe in Group B (p < 0.05). There were no significant differences in surgical time, blood loss or the other side effects between Groups A and B (p > 0.05). The percentage of pelvic tumor recurrences in Group A was lower than that of the patients in Group B (11.8% vs 20.0%) although with no significant difference at present. No distant metastasis has been found in both two groups. CONCLUSION Except for less abdominal pain and pelvic adhesions, 252Cf neutron brachytherapy has perioperative effects similar to those of neoadjuvant intra-arterial embolism chemotherapy.

Abstract
OBJECTIVE To evaluate the role of the combined periodontic-orthodontic treatment in the esthetic reconstruc- tion of the anterior teeth area following periodontitis. METHODS Thirteen adult patients with anterior teeth displacements were treated. The probing pocket depth (PD; 102 teeth, 612 sites), bleeding on probing (102 teeth, 204 sites), papilla index (PI; 128 papillae), and papillary height (PH; 128 papillae) of each patient were assessed at baseline, 3 months after the initial therapy, and the end of the orthodontic treatment. Non-parametric and paired-sample t tests were carried out for the statistical analysis of the data. RESULTS Three months after initial therapy, the sites with PD ≤ 3 mm accounted for 79.58% (487/612) of the observed teeth, and 88.73% (181/204) of the buccal and lingual sites of the teeth showed negative bleeding on probing. These findings were better than those at baseline [26.31% (161/612) and 22.06% (45/204), respectively] (P < 0.05), but no sig- nificant difference was observed compared with pro-orthodontic treatment (P > 0.05). Prior to orthodontic treatment, the levels of the PI of 8 and 21 papillae were III and II, respectively, among the 128 observed papillae. After the orthodontic treatment, 51 papillae were at level III and 68 papillae were at level II. The PH of the 102 papillae was 2.84 mm ± 0.62 mm after ortho- dontic treatment. This result indicated significant difference compared with that of pre-orthodontic treatment (1.69 mm ± 0.57 mm) (P < 0.05). CONCLUSION After initial therapy, moderate orthodontic teeth movements may reconstruct the interproximal soft tissue, with esthetic improvement of the papillary level and resolution of the periodontal defects.

Abstract
Endoplasmic reticulum (ER) homeostasis is crucial for beta-cell function and survival. Direct as well as indirect evidence has pointed toward Ca(2+) as an important determinant of interleukin-1beta (IL-1beta)-induced beta-cell dysfunction and apoptosis. In the present study, we show that IL-1beta-induced apoptosis and necrosis in primary rat beta-cells and MIN6 cells largely depends on ER stress, ER Ca(2+) release, and c-Jun N-terminal kinase (JNK) activation. beta-cells also showed marked sensitivity to apoptosis induced by sarcoendoplasmic reticulum Ca(2+) ATPase (SERCA) blockers, thapsigargin and cyclopiazonic acid (CPA). IL-1beta induced ER Ca(2+) release, which was paralleled by an IL-1beta-dependent induction of JNK activation and the ER stress response, including activation of PRK (RNA-dependent protein kinase)-like ER kinase (PERK). Furthermore, reduced activation of JNK, utilizing JNK inhibitor SP600125, resulted in significant protection from IL-1beta- or thapsigargin-induced apoptosis via ER stress. In conclusion, our results suggest that the IL-1beta-induced depletion of ER Ca(2+) and activation of the ER stress via JNK pathway are potential contributory mechanisms to beta-cell death.
